A Preliminary Investigation into CNO Availability Schedule Overruns

A naval vessels availability is a scheduled period of time, normally conducted in a shipyard, to perform maintenance on and modernization of the vessel and its systems. The four public naval shipyards are continually challenged to complete depot-level, CNO availabilities on schedule. A naval vessels late return to the fleet results in the decrease in operational readiness due to the reduced number of operational days available for these vessels. Subject-matter experts hypothesize that factors such as inadequate planning for resources, quantity of overtime, and quantity of work stoppages experienced contribute to availability lateness. Data collected by the shipyards are analyzed to investigate factors influencing late completion of availabilities. The analysis suggests that carrier availabilities tend to finish on schedule more often than submarine availabilities, timely availabilities tend to have a higher cost performance ratio than late availabilities, late availabilities tend to charge less for work per month in man-days than the budgeted amount of planned work, and availabilities that finish on schedule tend to have fewer work stoppages prior to start of the availability than the later completing ones.
